Abstract:
Optical adaptive viewport display systems and methods are provided. One such optical adaptive viewport display system has an adaptive pupil device which is optical coupled to an optical combiner. The adaptive pupil device is optically couplable to an image projector and is configured to select a sub-pupil from the pupil of the projector. The selected sub-pupil is optically relayed by relay optics from the adaptive pupil device to an eyebox. The relay optics includes an optical combiner. The sub-pupil size and position is selected by the adaptive pupil device so that an optical image spot beam from the sub-pupil and reflected by the optical combiner on to the eye box has a diameter at the eyebox such that the virtual image, as seen by a human eye disposed at the eyebox, is hyperfocused.
